serological cross-sectional study of paratuberculosis in cattle in austria.from 1995 to 1997, the prevalence of serum antibodies against mycobacterium avium subspecies paratuberculosis (m. av. ssp. ptbc.)--the causal agent of paratuberculosis (johne's disease)--was examined in 11,028 austrian cattle. samples from the four oldest cattle on 2757 farms were collected according to a specific sampling schedule for this epidemiological study. district, age and breed of animals were included as variables in this study. for antibody screening against m. avium subspecies paratu ...199910528542
[mycobacterium avium subsp. paratuberculosis in wild animal species and cattle in styria/austria].infections with mycobacterium ovium ssp. paratuberculosis (m. paratuberculosis) are increasingly recognised worldwide. in addition to an increased prevalence of paratuberculosis in austrian cattle herds, recent years have also shown a rise in infections with m. paratuberculosis in wild red and roe deer, chamois and mouflon. during the period from june 2002 to september 2004, mesenteric lymph nodes were taken from a total of 483 wild animals hunted or found dead and from 338 deceased cattle. samp ...200516048043
multiple strain infections and high genotypic diversity among mycobacterium avium subsp. paratuberculosis field isolates from diseased wild and domestic ruminant species in the eastern alpine region of austria.johne's disease, or paratuberculosis, is a chronic fatal ruminant gastroenteritis caused by mycobacterium avium subspecies paratuberculosis (map) whose foodborne zoonotic potential and association with crohn's disease are still under debate. the disease is widespread but its epidemiology and epizootiology remains elusive. wildlife is suspected to play a major role. after a surge in map seroprevalence in austrian cattle, paratuberculosis was declared a notifiable disease in austria in 2006. at th ...201424270014
